2.5 Power Connection and ON/OFF
WARNING
• To prevent the possibility of electric shock when wiring, confirm that the power
supply source is turned OFF.
• To prevent an electric shock or fire, use only power cords supplied by
YOKOGAWA for the MX100.
• Make sure to perform protective earth grounding to prevent electric shock.
Connect the power cord for the MX100 to a three-prong power outlet with a
protective earth terminal. The AC outlet must be of a three-prong type with a
protective earth ground terminal.
Do not use the functional ground terminal (see section 2.2, “Installation”) as a
protective earth terminal.
• Do not use an extension cord without protective earth ground. Otherwise, the
protection function will be compromised.
Use a power supply that meets the conditions indicated below.
